3.2  Connecting DCM300 to a computer 
Once your hard drive is installed in DCM300, you are ready to use it with your computer. 
To do so, follow these easy steps: 
1.  Insert the USB or Firewire 400/800 connector to 
your computer’s corresponding port. 
2.  Insert the USB or Firewire 400/800 to DCM300’s 
corresponding port. Ensure correct connector 
orientation to obtain a snug fit. 
3.  The unit’s backlight will turn on, indicating that 
DCM300 has powered up. 
Notes on using USB port: 
•  Do not attempt to use DCM300 when connected to a bus-powered USB hub or USB 
extension cable. 
•  Connecting to a non-USB compliant port may cause operation damage or failure.  
•  If insufficient power to DCM300, connect both connectors of the USB Y-cable to the 
computer’s USB ports. 
•  To achieve USB 2.0 speeds, always connect DCM300 to a USB 2.0 Hi-Speed port. 
Notes on using Firewire port: 
•  If you are using Firewire 400, please ensure that you have a 9-to-6 pin bilingual cable 
and connect the 6 pin end to the computer’s Firewire port.
